<P>PROBLEM TO BE SOLVED: To minimize a failure model by using another software program for assessing more accurately, for a reason that failure tree analysis by a top-down event in a probabilistic risk assessment cannot unconditionally summarize calculations because of a difference in probability of occurrence due to different events. <P>SOLUTION: The invention provides a kind of standardized computer support risk quantitative assessment method, creates a failure tree model by top-down logic which arranges the appropriate events in series, and sets a command of a predetermined value. A program for the invention elucidates characteristics included in event series, renames a fundamental event, and further, calculates a rational minimum cut-set, a risk result and a criticality index by substituting a parameter of the fundamental event for an assessment model. And by adjusting the parameter of the fundamental event, the program performs sensitivity analysis which the fundamental event fails, for elaborating best measures. <P>COPYRIGHT: (C)2012,JPO&INPIT |
